Welcome to My Homelab Projects
Hi, I’m Sanju Mathew. I’m a junior DevOps/SRE candidate with a strong foundation in Linux administration and in building and documenting secure, production-grade infrastructure through self-directed homelab projects. I hold AWS certifications and have hands-on experience designing, deploying, and operating containerised workloads using Kubernetes, Docker, and Infrastructure as Code (Terraform/CloudFormation), with monitoring and alerting built in from the start.
I focus on repeatable deployments, monitoring/alerting, and clear documentation.
This site documents the projects I’ve built, the architectural decisions behind them, and what I learned while troubleshooting and improving reliability.
